Weight loss

I am 54 year old male with good health. I had checked my weight 6 months ago and it was 140 lbs. I have had bad flu/cough/cold for the past 2 weeks. I am also taking antibiotic for throat infection. When i checked my weight couple of days ago, it showed 120 lbs. I do feel fine ohterwise. What could be the cause of this weight loss? I am not diabetic.
